LGTM, but I think it's worth renaming "addKnownUnique"
That functions name has lost its meaning over time. Either in
this patch or another patch.

I completely agree. I came here just to write this comment!

I haven't been able to come up with a good alternative name, since "addKnownUnique" looks like it makes a lot of sense in the other place it's used

I'll look at the other call sites later today, but just off the top
of my head, what about "append" or "addUnconditionally"?

I've gone with "addUnchecked()", let me know if that works for you guys

I think the name addUnchecked is OK for now. We should return later and consider renaming the other "add" functions to make it clearer that they enforce uniqueness. Since uniqueness is no longer an invariant of the class, the add function needs to make it clear that it’s a rule it implements.
